Medium sized, robust species; body light to dark brown ( Fig. 8B ). Head black, distinctly transverse, with eyes medium sized (EyL/TL = 1.50–1.67 (1.56)); microsculpture of transverse waves; no interocular punctures between anterior frontal punctures (cf. Fig. 6F ); antennae pale reddish, antennomeres elongate; palpi pale reddish. Thorax: pronotum light to dark brown, slightly wider than long, wider than head, with microsculpture of transverse waves; three punctures in dorsal row and one to two in sublateral row with its posteriormost puncture reaching just beyond the level of first puncture of dorsal row; scutellum punctured and pubescent; elytra most often reddish brown rarely fully darkened, uniformly pubescent, slightly wider than long, roughly same length as pronotum; legs reddish brown with inner face of tibia darker. Abdomen light to dark brown, tergites uniformly punctured, without clear iridescence. Male. Aedeagus ( Fig. 13F ): paramere spatulate with clear proximal to medial attenuation and extending into paddle-like structure near apex, reaching just beyond apex of median lobe, with sensory peg setae forming a broad horseshoe shaped band of relatively large peg setae; median lobe broad with gentle constriction to a point at apex, on parameral side with two small teeth pointing slightly basad, positioned at level near basal level of peg setae band of paramere; internal sac without a continuation of C-sclerite. Differential diagnosis. Quedius meridiocarpathicus is very similar to other species in the molochinus -group with red elytra, viz Q. molochinus , Q. balticus , and Q. vicinus . It can be distinguished from Q. balticus by the pale base of the basal three antennomeres. Generally, it has paler middle antennomeres compared to Q. molochinus . Compared to Q. vicinus it is generally slightly darker, elytra brownish red (pale red to yellowish in Q. vicinus ), abdomen dark brown (light brown in Q. vicinus ). For confident discrimination of these species, their genitalia should be checked: the aedeagus of Q. meridiocarpathicus differs from Q. molochinus in the absence of an extension of the C-sclerite in the internal sac, in the spatula-shaped paramere with clear proximal to medial attenuation, and larger peg setae. It can be distinguished most easily from Q. balticus by the shape of the paramere, which is medially broadened in Q. balticus and broadened towards apex in Q. meridiocarpathicus . It differs from Q. vicinus in the absence of a blunt apical hook on the paramere (parameral side). Quedius meridiocarpathicus can be confused with Q. picipes of the subgenus Raphirus , which may occur in similar environments. It can be readily distinguished from the latter by more parallel-sided abdomen and entire labrum. Synonymic notes. Independent of each other, Sආൾඍൺඇൺ (1958) and KඈඋGൾ (1960b) recognized that a species very similar to Q. molochinus was present in Southeastern Europe. KඈඋGൾ (1962) himself synonymized Q. dalmatinus Korge, 1960 with Q. meridiocarpathicus Smetana, 1958 . Based on the description and illustration of Q. dalmatinus , it clearly agrees with the concept of Q. meridiocarpathicus herein. Bionomics. Quedius meridiocarpathicus appears to be found most frequently in wet debris and under rocks near water bodies, both fresh and saline. We (AKH and AS ) have collected this species in the flood debris of a salt lagune near Bibione, Italy , in debris around the stagnant salt pond near the beach of Fokiano, Greece ( Fig. 2C ) and on the marsh debris near the Gefest Mud Volcano in the Taman Peninsula in southern Russia . Like many other Quedius s. str. , the species is found at lower elevations in the northern part of its range and at much higher elevations (up to 2000 m ) towards the southern part of its range. Distribution. Quedius meridiocarpathicus is distributed from Italy through Southeastern Europe to the Crimea, Western Caucasus and Anatolia ( Fig. 20 ). There seem to be rather well defined distributional boundaries between this species, and Q. molochinus and Q. vicinus . The northern range of Q. meridiocarpathicus is roughly delimited by the Alps and Carpathians, where it is replaced by Q. molochinus to the North of these mountain chains. The species continues north around the Black Sea to the western foothills of the Caucasus. To the South it extends to northern and western Anatolia , mainly along the coast, but it is also found more inland in some sites. In southern and eastern Anatolia Q. meridiocarpathicus is gradually replaced by Q. vicinus , with which it seems to co-occur to some extent in southern Anatolia .
